` or lin s when the slide is at rest.

A further object Vof my invention is to provide a slide for fasteners of the character stated, which will not only permit the operating tab or handle member to lie flat and within the plane of one 'of the wings of the body of the slide, but it will also leave the top or outer wing of the body of the slide clear and unobstructed by any handle member or projections or indentations or structural elements, -so that the outer wing member of the body ofthe slide may present a clear and unobstructed panel which may be utilized for ornamentations of various kinds. Thus, it is an object of my invention to form a slide for fasteners ofthe character stated in which all the functional elements of slide and handle are 'so arranged and related as to leave both the outer wing member of the slide as well as the operating handle member entirely clear and subject to ornamentation.

ly; an upright portion joining the upper and.

the lower wings; a finger tab pivoted about the sides of the upper wing in a manner -to permit said tab to lie in the same plane as said upper wing, when said tab is not being operated and is in a downward position; and a locking-pin projecting from the under surface of the finger tab, adapted to engage and reliable results, although it is to be understood vthat the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring to the drawing in which like reference characters indicate like parts:

According to my invention, I provide two rows of scoops 6 and 7 joined and interlocked,

as at 8, by means of a slide 9. The slidejdisY preferably pressed out of a single piece of metal so as to form an upper wing 10, alovier wing 11, and an upright wing-retainingfspacer member 12.v A i A central groove 13, forked at 14 into two smaller divergent grooves 15 and 16 respectively, is pressed out of the interior face of each wing, so as to accommodate therebetween and therein a row of interlocked scoops and two rows of disengaged scoops, respectively ;-the rows of scoops disengaging each other 'about the upright spacer member 12.

The upper wing 10 is slightly thickened at each df two opposite side portions 18'and 19 respectively and suitable opposite and axially aligned journal openings are provided to accommodate two opposed and axially aligned trunnions 20 and 21 projecting inwardly from the two leg portions 22 and 23 respectively of the linger tap 17. The leg portions 22 and 23 are long enough to permit the linger tap 17 to swing clear of the end of the upper wing nearest the interlocked scoops, and to permit the 5 finger tab to lie in the same plane as the upper wing.

Y A locking-pin 24 projects from a point along the centerline of the finger tab 17 on the face nearest the interlocked scoops.

The linger tab 17, the legs 22 and 23, and the trunnions and 21 are preferably formed integrally and pressed out of one piece of metal, the trunnions being sprung or pressed into the journal openings in the sides of the upper wing 10.

I may also provide a pair of opposed detents 25 on the inner faces of the legs 22 and 23; said detents 25 being adapted to press against the sides of the upper wing 10 when the finger tab 17 is swung into the locking position, thereby frictionally to retain said finger tab in the locking position. I may provide also, a. pair of opposed notches 26 on the side of the upper wing, and so disposed therein as lso-receive the detents 25 when the finger tab 17 is swung into the locking position, tending more securely to lock saidlinger tab in said locking position. (See Fig. 6)

In use, the slide is drawn over the scoops by means of the finger tab, which may be swung through a wide arc about the trunnions 20 and 21. When the slide is in its desired position along the scoops, the finger" tab is pressed against the interlocked scoops, as shown in Figure 2, thereby forcing the locking-pin 24 between the engaged scoops operatively to lock the slide against the same.

' In Figures 3, 4 and 5 modified embodiments of my invention are shown, illustrating the 40 manner in which the exterior shape of the slideJ may be varied; Figure 5 being a sectional view.

It will thus be seen that by my invention, I am enabled to unite the handle member and the body of the slide without any projections or obstructions. on the face of the slide and so that the handle member might also lie in the plane of one of the wings of the slide, when not in use.

Further by means of my invention, the locking of the slide is assured whenever the linger tab is thrown into the inoperative position, there being but one position in which the linger tab is out of the way, namely the locking position.

I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in allA respects as illustrative and not restrictive, reference being had tothe appended claims rather than to the foregoing description to indicate the scope of the invention.
